Low-Cost Strider For Guatemala, Nicole Catherine Cooper, Gonzalo Hernandez, Jared W. Tower

Mechanical Engineering

The purpose of this project was to create a strider, a type of standing rehabilitation device, for children in developing countries who have trouble walking and supporting their full body weight. The project was initially brought to us by Cal Poly professor Brian Self, who had visited a clinic in San Marcos and determined that there were children there who had difficulties with walking and were a need for a rehabilitation device. The team discussed the problem with Dr. Self, Matt Robinson (a local San Luis Obispo prosthetist), and Cal Poly physics professor Pete Schwartz, all of whom had visited …

Biomechanical Analysis Of Gait Kinetics Resulting From Use Of A Vacuum Socket On A Transtibial Prosthesis, Maria De Lourdes Ramos Gonzalez

Honors College Theses

The technology and design of lower limb prosthetics have evolved greatly since their introduction. The current study proposed to compare the effects of a conventional pin socket attachment and a vacuum socket attachment for a transtibial amputee. Whereas traditional measurements of gait utilize force plates and camera systems, this study made use of a small tri-axial load cell located at the base of the socket to measure the forces and moments exerted during a regular gait cycle. The hypothesis tested stated that a vacuum pump socket attachment, when compared to a non-vacuum (pin) socket, will have a significant effect on …

Efficacy Of A Carbon Fiber Orthotic Toe-Off Brace In Adults With Cerebral Palsy, June Kume, John R. Magel, Erin Dicandia, Justine Hoffman, Robert Issing, Joshua Little, Tyler Roden

The School of Health Sciences Publications and Research

Purpose/Hypothesis : This pilot study evaluated the effects of a unique carbon fiber ankle/foot orthosis for individuals diagnosed with foot drop (“Toe-Off” design, Allard USA, Inc). We hypothesized that use of this brace would be useful for adults with cerebral palsy (CP) as evidenced by improved gait characteristics including gait endurance and balance.

Number of Subjects : A convenience sample of 4 patients, between the ages of 29 and 55, with diagnoses of cerebral palsy, was successfully recruited from United Cerebral Palsy (UCP) of Suffolk (Central Islip, NY). All individuals received regular physical therapy at UCP prior to and throughout …

Its All In The Mind: Mind Controlled Prosthetics, Tziril Joselit

The Science Journal of the Lander College of Arts and Sciences

The problem with prosthetics is a longstanding problem that researchers have been working on for many years. They are attempting to create a prosthetic that acts as if it is the original limb or body part. In recent years they have discovered a technology that has assisted many of those who are greatly in need of a prosthetic, such as an amputee or someone who is “locked in”. “Locked in” refers to a person who is technically confined in his own body and has no methods of communication with the world. Brain-computer interface (BCI) has opened up a whole new …

The Viability Of Organ Printing, Estie Schick

The Science Journal of the Lander College of Arts and Sciences

Organ printing is an emerging technology that can potentially replace the need for human organ transplants altogether. Organ printing uses bioprinting methods to create three-dimensional biological constructs. Although it has not yet been implemented successfully, with nearly two decades of research devoted to this area, much progress has been made. This article outlines the various aspects of the organ printing process, describes both the accomplishments and challenges of bioprinting, and discusses the feasibility of bioprinting as a viable method for organ replacement.
